Embodiment 1

[0047] (1) Compost domestic waste first to remove all kinds of wood, plastic, glass, metal and other sundries, then dry it at 105°C to constant weight, and sieve compost with a particle size of 1700nm. Compost with a particle size of 1700nm Pulverize under 24000 rev / mins, and the time is respectively 1min, 2min and 3min, to prepare the rubbish micro-fertilizer of different particle size, with S4800 field emission scanning electron microscope (S4800, JAPAN) micro-fine municipal solid waste compost particle size is respectively 1200nm, 600nm and 300nm. Then it was dried at 105°C to constant weight, and sieved by standard sieves with different apertures to obtain compost with a particle size of 1700nm; compost with a particle size of 1700nm was crushed at 24000 rpm to prepare compost with a particle size of 1200nm, 600nm and 300nm waste micro-fertilizers with different particle sizes;

[0048] Among them, the organic matter content in the compost is 22.00%, and the bulk density ...

Embodiment 2

[0052] Others are the same as Example 1 and then in each pot of 180g soil, 3g, 1200nm, 600nm or 300nm garbage micro-fertilizers are evenly sprinkled on the soil surface, and finally 20g of soil is evenly covered on it; each pot is sowed with 0.5g of ryegrass, and the temperature The temperature is 26°C, the relative humidity is 40%, and the light is natural light penetrating into the room; at the initial stage of sowing, water fully to ensure the smooth germination of the seeds and the initial growth of the seedlings. After two weeks, water according to 65% of the field water capacity. After that, weigh and water every one to two days to maintain the stress range, and start to measure the indicators on the 44th day.

Embodiment 3

[0054] (1) First remove all kinds of sundries from the municipal solid waste compost, then dry it to constant weight at 105°C, and sieve out the compost with a particle size of 1700nm; crush the compost with a particle size of 1700nm at 24000 rpm to prepare Produce waste micro-fertilizers with different particle sizes of 1200nm, 600nm and 300nm;

[0055] (2) Adopt diameter 7cm, the plastic basin of high 10cm, every basin 150g soil, sowing lawn plant 0.5g / pot, the rubbish micro-fertilizer that particle diameter is respectively 1200nm, 600nm and 300nm is spread evenly on soil surface, wherein particle diameter and The ratio of parts by weight of the soil is 1:60 times. Then sow 0.5g of ryegrass, the control temperature is 20~26°C, the relative humidity is 40%~60%, and the light is the natural light penetrating into the room; at the initial stage of sowing, fully water to ensure that the seeds can germinate smoothly and the initial growth of the seedlings, After two weeks, water...

Abstract

The invention relates to a method for improving antioxidant enzyme activity of ryegrass by adopting fine domestic garbage compost under drought conditions. The method comprises the following steps of: uniformly scattering garbage trace fertilizers with grain diameters of 1,200 nanometers, 600 nanometers and 300 nanometers respectively on the surface of soil, wherein the weight part ratio of the grain diameter to the soil is 1: 60-80; then, sowing 0.5 gram of tall fescue, controlling the temperature to be between 20 and 26 DEG C and relative humidity to be between 40 and 60 percent, and illuminating the tall fescue with indoor natural light; and fully watering the tall fescue at the initial sowing stage, weighing the water in an amount which is 55 to 65 percent of the field holding amount every day or every two days after two weeks to maintain the water in a stress range, and measuring each index on the 44th day. The method provides technical support for applying the fine-grain urban domestic garbage compost to a lawn planting system.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to the reasonable use of composting of municipal domestic garbage. More specifically, a method for increasing the antioxidant enzyme activity of ryegrass by composting fine domestic waste under drought conditions. Background technique [0002] Lawns play an important role in urban greening, environmental protection and ecological balance. The planting and maintenance of turfgrass requires a lot of water; the large demand for irrigation water makes the maintenance cost of turfgrass extremely high. develop. The traditional water-saving methods of lawns are through the selection of drought-resistant varieties, the economical irrigation amount of lawns and the selection of irrigation methods; water capacity. Jiao Jinchuan et al. studied the effect of potassium fertilizer on the drought resistance of ryegrass, and used the germination rate of ryegrass seeds, leaf thickn...
